Perceived exertion responses were compared between field-independent and field-dependent perceivers at three cycle-ergometer pedalling rates. 50 male subjects were classified according to mode of field approach on the basis of their performance on an embedded-figures test. Power output was held constant at 840 kpm/min., while pedalling rate was randomly set at 40, 60, or 80 rpm. Significant differences between the field-independent and -dependent groups were not found at the three pedalling rates for any of the physiological variables or for over-all, legs and chest ratings of perceived exertion. The extent of differentiated psychological functioning did not account for individual differences in perceptual reactance during muscular exertion. 相似文献

To ascertain whether there are ear-hemisphere asymmetries of selective attention, signal stimuli (tonal sequences) were presented monaurally with and without complex maskers (music and speech). The right ear-left hemisphere was more disrupted by language maskers; the left ear-right hemisphere was more disrupted by music maskers. These results suggest that there are hemispheric asymmetries of selective attention and that the ear hemisphere that usually processes a class of stimuli has greater difficulty filtering out those stimuli than does the nonspecialized hemisphere. 相似文献

The relationship of adolescent peer groups to the incidence of psychosocial problems 总被引:1,自引:0,他引:1
This study combined a treatment sample (n = 127) and a control sample (n = 114) of adolescents (ages 13-17) to investigate the relationship between adolescent peer groups and incidence of psychosocial problems. A content analysis resulted in four separate types of peer groups. The group with the lowest level of involvement in school activities was labeled by other adolescents in negative terms. An analysis of variance indicated that the least involved and most negatively labeled group generally had the most positive attitudes toward alcohol and drug use, the lowest levels of perceived harm due to alcohol and drug use, and the highest levels of alcohol abuse, drug use, delinquency, and depression. This group also had the lowest level of self-esteem, most external locus of control, least perceived access to occupational opportunities, and highest level of societal estrangement. The results are interpreted as providing support for both control and labeling theories. Implications for theory-based intervention are discussed. 相似文献

Is temporal order encoded automatically? 总被引:1,自引:0,他引:1
Rose T. Zacks Lynn Hasher Joseph W. Alba Henrianne Sanft Karen Caniglia Rose 《Memory & cognition》1984,12(4):387-394
The reported experiment tested the suggestion that encoding of temporal order is automatic. Specifically, two of Hasher and Zacks’s (1979) automaticity criteria were examined: (1) that the amount and appropriateness of practice received would not affect acquisition of temporal information, and (2) that reliable individual differences would not be found on a test of memory for temporal order. Contrary to expectations, neither of these criteria was confirmed: Retention of temporal order increased with practice at three (or four) successive lists. And, reliable individual differences were indicated by the findings that subjects’ relative performance levels remained stable across lists, and that groups with higher average academic ability outperformed those with lower ability. Similar results were obtained for a flee-recall task (in which case they were expected). Problems of assessing degrees of nonautomaticity are discussed. Our data are seen to be in general conformity with Tzeng’s (e.g., Tzeng & Cotton, 1980) “study-phase” retrieval theory of temporal coding. 相似文献

An adaptive approach for modelling individual-level choice among multiattribute alternatives using the binary logit model is presented. The algorithm involves the collection of paired comparison data. In an effort to maximize the amount of information obtainable from each response, it is based on the experimental design criterion of D-optimality. A simulation study indicates that the proposed algorithm outperforms other sequential selection approaches in terms of estimation accuracy and predictive efficiency under certain circumstances. The results appear to encourage the use of such an adaptive algorithm for individual-level modelling in light of the potential reduction in data requirements without significant loss in predictive accuracy. 相似文献

In this paper, we utilize GIS (Geographic Information System) mapping data to locate eleven immigrant congregations and the residential addresses of their members in Houston, Texas. Combining this information with ethnographic data allows us to understand how ecological variables impact organizationalcharacteristics of religious institutions. Specifically, we combine GIS and ethnographic data on immigrant congregations in Houston, Texas, to analyze characteristics that make them more parish or niche-like in structure. We demonstrate that the combination of GIS techniques and standard field methods yields the greatest potential to provide a comprehensive understanding of what congregations mean to their members. 相似文献
